FIRE-HOSE, NOZZLE.

SPECIFICATION forming part of Letters Patent No. 603,144, dated April26, 1898. Application filed January 25, 1896. Serial No. 576,886. (Nomodel.)

ranged to permit a fireman to throw a straight stream onto a fire or aspray of large diameter to extinguish the fire and to completely protectand shield the fireman.

'The invention consists principally of a casing containing a valvedstream-pipe and a circular spray-nozzle. a

' The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement with the valvefor the streampipe closed. Fig. 2 is a plan view of the same. Fig. 3 isa rear face view of the valve for the stream-pipe. Fig. 4. is asectional side elevation of the improvement with the valve for vthestream-pipe open, and Fig. 5 is a sectional plan view of the same onthe line 5 5 of Fig. 4.

The improved fire-hose nozzle is provided with a head or casing A,formed with an internal thread A for connection with the hose or playpipe, through which passes the stream of water. The outer end of thecasing A is formed with an internal thread A engaged by a ring B, havinga spider B for supporting the stream-pipe B, preferably arrangedcentrally of the casing, as plainly illustrated in the drawings, thelower-or inner end of said stream-pipe being beveled, as indicated inFigs. 1 and 4:, for forming a seat for the valve C,adapted to open andclose said streampipe. The internal thread A is also engaged by thethreaded inner end D of a conical nozzle D, formedwith anoutwardly-flaring mouth D arranged opposite a disk E, having a beveledouter edge corresponding to the flare of the mouth D so that said diskwill seat itself on the mouth D The disk E is loosely held on, thestream-pipe B, and its outward sliding motion is limited by a nut F,screwing on the'outer threaded end of the stream-pipe B.

The nozzle D is provided with a roughened external surface D forpermitting the fireman to turn said nozzle up or down in the thread A toincrease or decrease the outlet-opening at the mouth D and disk E,according to the spray desired to be thrown by the device.

The valve 0 is adapted to be opened and closed by the fireman,and forthis purpose the upper end of the valve is pivoted at O to one of thearms of the spider B and on the back I of said valve are arranged lugs 0having elongated apertures for the reception of a pin G, held in the eyeof a bolt Gr, screwing in a sleeve H, mounted to'turn in a stuffing-boxA held on the casing A and having an annular flange held between thestuffing-box and the capthereof whereby the sleeve may freely turn, butwill be prevented from longitudinal movement. On the outer end ofthe'sleeve H is secured a hand-wheel H for turning said sleeve, so as toscrew the bolt G inward or outward to open or close the valve G, as thecase may be.

Now it will be seen that by the arrangement described the stream ofwater passing into the casing A can be passed either in spray form pastthe nozzle D and disk E or it can be passed through the stream-pipe B atthe time the valve 0 is open and the nozzle D is closed. (See Fig. 4.) aIf desired, the nozzle D and the stream-pipe B may be opened to force acentral stream through the pipe B and a spray through the nozzle D, soas to protect and 0 shield the fireman.

It is understood that when the nozzle D is screwed inward and the waterpasses into the casing A under pressure then the disk E is forcedoutward from the pipe B until it rests against the nut F to permit thewater to pass through the nozzle spray-openin g between the disk E andthe mouth D It is further un derstood that the spread of the spray isregulated by the operator adjusting the nozzle D.

The valve 0 and the disk E may be made plain, as shown in Fig. at; butwe prefer the construction of the valve and disk shown in Fig. 1, inwhich the valve 0 is provided on its face with a packing-disk C ofleather or like material, to tightly close the lower end of thestream-pipe B. The disk E (shown in Fig. 1) is provided with the bodypart E, on the top of which rests a gasket E held in place by a threadedring E screwing on the upper reduced end of the said disk. Apacking-ring or gasket E is fitted into a recess in the lower end of thebody E to fit snugly on the streampipe B.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent 1. A nozzle having a casing, a portion of whichis internally threaded,a threaded spider cooperating with the threads ofthe casing, a stream-pipe carried by the spider, the outer end of thestream-pipe projecting beyond the casing, a disk carried by thestream-pipe, and a nozzle proper having a threaded portion cooperatingwith the threads of the casing, the nozzle proper being capable ofmovement toward and from the disk, substantially as described.

2. A nozzle consisting of a casing having a tapering inner portion and acylindrical inner portion, the cylindrical portion being internallythreaded, a spider having threads cooperating with the threads of thecylindrical portion, a stream-pipe carried by the spider and projectingbeyond the cylindrical portion of the nozzle, a disk carried by theouter end of the stream-pipe, a tapering nozzle proper having ascrew-threaded portion cooperating with the threads of the cylindricalportion of the casing and being capable of movement toward and from thedisk on the stream-pipe, and means for controlling the stream-pipe,substantially as described.

3. In a nozzle, the combination with a cas ing having a bearing and captherefor, of a stream-pipe, a hinged valve capable of closing thestream-pipe, an internally-threaded sleeve having an annular collar, thesleeve being revolubly held within the bearing and the collar engagedwith the cap thereof, and a bolt connected to the valve and cooperatin gwith the threads of the sleeve, substantially as described.

4. A nozzle having a casing, a portion of which is internally threaded,a threaded spider cooperating with the threads of the casing, astream-pipe carried by the spider and projecting out of the casing, adisk held on the stream-pipe, a nozzle proper having adjustableconnection with the casing and capable of movement to engage anddisengage the disk, and a valve commanding the streampipe, substantiallyas described.

5. A nozzle having a casing, a stream-pipe held within the casing andhaving a diagonal inner end, a disk carried by the stream-pipe, a nozzleproper adjustable on the casing and capable of engaging and disengagingthe disk, a valve pivotally mounted adjacent to the inner diagonal endof the stream-pipe and capable of moving to close or open the same, andmeans extending through the casing by which the valve may be operated,substantially as described.

6. A nozzle having a casing, a stream-pipe held within the casing andextending out of the same, a disk carried by the stream-pipe, a nozzleproper movable on the casing to engage and disengage the disk, apivotallymounted valve capable of movement to open and close thestream-pipe, and means extending through the casing by which the valvemay be operated, substantially as described.
